A potent analytical method known as gas chromatography-mass spectrometry (GC-MS) blends the detection and identification skills of mass spectrometry with the separation capabilities of gas chromatography. Numerous fields, such as environmental analysis, forensic science, drug testing, and food safety, frequently use GC-MS. The GC column is one of the most important parts of a GC-MS system and is essential to the process of separating various substances in a sample about 

A stationary phase that is placed into GC columns interacts with the molecules of the sample as it moves through the column. Because various compounds have varying affinities for the stationary phase, their chemical characteristics can be used to separate them. Selecting the right GC column is essential to getting good separation and
